When running a script that spools the records to a file, Toad freezes up. This only happens when there is a large number of records. It actually creates the file and exports all the output to the file, but once it gets to the end of spooling Toad shows a dialog box that says something about processing output for grid. If the script output grid is turned off then a different dialog box is shown saying processing statement and it still freezes up.
WORKAROUND:
The file is created, so user just needs to kill Toad, via the Task Manager, and go get the file that the spool created.
STATUS:
Waiting for fix to be released in a future version of Toad for Oracle.
